Does being at altitude make you dehydrated?
Does being at altitude make you dehydrated? According to the Wilderness Medical Society, your body loses water through respiration at high altitude twice as fast as it does at sea level. High altitude hiking, running, backpacking, and biking can also make you need to urinate more often and can also stop your thirst response, increasing your risk of dehydration.
What should you not do at high altitude?
Do not drink alcohol or do heavy exercise for at least the first 48 hours after you arrive at an elevation above 8,000 feet. Traveling to elevations greater than 9,000 ft for 2 nights or more, within 30 days before your trip, can help avoid altitude illness on a longer trip at a high elevation.
